Tylenol and aspirin reduce fever. Which pharmacologic class do they belong to?

Explanation:
Fever reduction is the defining action of antipyretics. These drugs work by acting on the hypothalamic thermoregulatory center and lowering the prostaglandin-mediated set point that drives fever. Tylenol (acetaminophen) reduces fever mainly through central COX inhibition, giving effective fever relief with little anti-inflammatory effect. Aspirin also lowers fever by inhibiting COX and decreasing CNS prostaglandin production, which brings down the fever set point. While aspirin has anti-inflammatory and analgesic properties, the common therapeutic category that describes both drugs’ ability to reduce fever is antipyretic.
